Add QEMU x86_64 platform support and various enhancements

- Introduced a new configuration file for QEMU x86_64 platform.
- Updated build scripts to accommodate changes in linker script generation.
- Enhanced Cargo.toml for x86-qemu-q35 platform with additional dependencies and features.
- Implemented multi-processor booting with support for application processors.
- Added APIC support for interrupt handling and timer management.
- Created boot and console modules for kernel initialization and UART communication.
- Developed memory management functionalities, including physical memory information retrieval.
- Implemented time management using TSC as the clock source.
- Added power management functionalities for system shutdown and CPU bootstrapping.
- Updated linker script to include driver registration sections.
- Created a new script for QEMU x86_64 execution with appropriate arguments.
